Watch a skateboarder balance on the edge of a skyscraper in Hong Kong

Here’s an idea for what’s probably the most dangerous sport ever thought of: urban climbing and skateboarding. Or at least that’s what urban climber/skateboarder Cheung Jai just gave us a glimpse into with one of his latest stunts.

High above the streets of Hong Kong, Jai is seen toying with a drop-in of death on the ledge of an unidentified skyscraper. He then goes for an axle stall before coming down from the ledge.
